  • adjusting elements upon pivoting of the adjusting element in one direction, engages either a date disk or an hour wheel and causes a shifting of the engaged disk or wheel.
  • the return spring will bring the adjusting element, in
  • the return spring is developed and arranged in such a way that, in case of a movement of the adjusting element from its rest position, the spring becomes cocked or stressed. This cocking develops a return force. This return force will reach a maximum watches, is indispensible.
  • the adjusting element may consist of a pivotably mounted adjusting disk, whose plane lies in a plane generally parallel to that of a date disk.
  • This adjusting disk is provided with two bent lobes, one of which engages with teeth provided on the date disk or the hour value upon passing a certain position of the adjusting wheel, while the other lobe engages a return spring.
  • the latter lobe acts as a stop to limit the pivotal movement of the adjusting disk.
  • the adjusting element may be fixedly arranged in relation to' an axial direction and may be coupled with a setting shaft by means of a coupling operated by axial shifting of the setting shaft.
  • the adjusting element may be arranged to be shiftablejn an axial direction by the setting shaft. In either case, the adjusting element may be capable of being brought into the area of the date disk or the hour wheel, according to choice.

  • FIG. 9 is a partial top view according to FIG. 8 showing the setting shaft shifted into engagement with the driving mechanism for the watch hands.
  • a setting shaft l3penetrates the bed plate 1 land has a bore at its end 13c. This bored end of shaft 13 is axially shiftably and rotatably mounted on a peg 21, which is fixed in the bed plate 10.
  • the peg 21 carries a collar 22 on which an adjusting disk 16 has been mounted rotatably.
  • This adjusting disk 16 is provided with two bent lobes 16a and 16b which engage with two elongated holes 10a and 10b provided in the bed plate 10. At the same time, at least one edge of the elongated hole 10b serves as a stop for the bent lobe 16b which is acted upon by return spring 20.
  • the return spring is supported on a pillar 19, and in addition to biasing the bent lobe 16b, also biases a locking pawl 18, with its end 20a, into engagement with the teeth bearing inner rim of a date disk 17.
  • This return action may entail a clockwise movement of disk 17 when cam 16a engages the next following or succeeding tooth. However, this clockwise movement will be permitted and immediately followed by a fully restoring counterclockwise movement, due to the resilient, self-centering action of pawl 18 in relation to the two diskteeth with which it is engaged.

  • the adjusting disk 36 can be seen in detail in FIG. 4. As shown, the adjusting disk 36 is held with the help of a screw nut 46 on the end 33 of the setting shaft 33d of the setting shaft 33.
  • the adjusting disk 36 contains an elongated hole 36a with which a peg 51 on the bed plate 30 engages. Engagement of the adjusting disk 36 with the peg 51 establishes a limiting position of the pivotal movement of the adjusting disk 36.
  • a spring 52 has been provided which is attached on the adjusting disk 36 and which serves as a peg position indicating spring.
  • the adjusting disk 36 carries two bolts 47 and 48 on which two latches 49 and 50 have been mounted for pivotal movement. The latches are resiliently held in the rest position shown in FIG. 4 by one common spring 53, in which position they are supported with their arms 49b and 50b on the screw nut 46.
  • Spring 52 has one end 52a anchored on disk 36 and another movable end 52b. Outward movement of end 52b may be restrained by a disk flange 52c, as shown in From the position shown in FIG. 4, the disk 36 is pivoted in a clockwise direction. After overcoming a certain pressure point which is produced by the spring 52 in cooperation with peg 51, arm 49a of latch 49 is moved against a tooth A of the date disk 37, as a result of which the latter is turned in a clockwise direction. When the movement of the disk 36 is reversed under the influence of the shaft 33, the latch 49 will be pivoted in a clockwise direction about bolt 47 upon contact of the latch arm 49a with the next following tooth of the date disk 37.
  • the latch 49 is guided across the latter tooth under the influence of the returning force of the spring 52 and may come to rest, disengaged from any tooth or disk 37. Through a repeated pivoting movement of the disk 36, his possible to move the date disk further by any desired number of steps. In the position of the disk 36 as illustrated, the latch arm 49a is not engaged with a tooth of the date disk 37.
  • An adjustment of the hour wheel 42 can be accomplished in a manner similar to thatdescribed above for adjusting the date disk, by first outwardly shifting the setting shaft 33 so that spring bar 34 engages groove 33b.
  • resiliently braced tooth 50 will advancingly cooperate with a toothed periphery of wheel 42, in the same manner that tooth 49 cooperates with the toothed rim of disk 37.
  • FIGS. 5 and 6 show another embodiment of the invention.
  • the bed plate has been designated by 60
  • the bridge by 61
  • the setting shaft is 63, which in this case has been provided with two grooves 63a and 63b, with which the spring bar 64 can engage.
  • the setting shaft 63 may assume two positions in an axial direction.
  • the setting shaft 63 otherwise has been mounted pivotally and longitudinally shiftably on a rotatable peg 76.
  • the peg 76 is connected firmly with the adjusting disk
  • a tooth coupling or axial clutch 82 has been provided between the setting shaft 63 and the peg 76, which in the position of the setting shaft 63 shown in the Figure is closed, so that a transmission of the torque to peg 76 and thus to the adjusting disk 66 takes place.
  • This adjusting disk 66 can be seen best in FIG. 6. Essentially, it is like the adjusting disk 36 according to FIG. 4. It carries two bolts or pins 77 and 78 on which the latches 79 and 80 have been mounted for pivotal movement. These latches have been connected with one another and jointly biased into a rest position by way of a spring clip 73.
  • the adjusting disk 66 in addition contains an elongated hole 66a into which a peg 71, arranged firmly on the bed plate 60, protrudes. Laterally from this elongated hole 66a, a cam 66b has been bent out of the disk 66. Cam 66b forms a stop for the return spring 72.
  • the return spring 72 has a U-shaped form and normally holds stop 66b and thereby the adjusting disk 66 in a middle position,'in'which no engagement takes place withthe date disk 67 nor with the hour wheel 72.
  • the stop 66b When the adjusting disk 66 is turned from themiddle position into the position shown in FIG. 6, in which an adjustment of the date disk 67 takes place, the stop 66b will press with one edge against a leg of the spring 72, while the other leg fits against the peg 71.
  • the spring 72 is dimensioned such that whenthe setting shaft 63 is pivoted to thereby cause the adjusting disk 66 to pivot from its middle position to its limiting position against peg 71, a spring force is exerted to prevent accidental adjustment of the hour wheel when adjustment of the date is taking place. This is so because the spring force will return the adjusting disk to the rest or middle position.
  • the spring will be mounted on disk 66 so that the U-shaped extremity is fixed to the disk and the legs of the spring are operable to engage opposite ends of rim 66b and thereby tend to resiliently Center" rim 66b relative to peg 71, i.e., maintain peg 71 adjacent the intermediate portion of slot 66a.
  • latches 79 and 80 will permit the spring 72 to induce the aforesaid disk restoring action.
  • the time zone adjustment of the hour wheel may take place by a pivoting of the setting shaft 63 in the opposite direction.
  • the latch 79 engages with a toothed periphery of the hour wheel 83 and causes it to pivot in relation to the second hour wheel 84 as in the case of the FIG. 34 embodiment.
  • the method of operation is the same as in the case of the design given by way of example according to FIGS. 3 and 4, so that this does not have to be discussed here in more detail.
  • FIGS. 7 and 9 corresponds substantially to that according to FIGS. 5 and 6.
  • the essential difference is the arrangement of the setting shaft 103, which here runs parallel to the dial of the watch.
  • a pair of gears is -shifted via levers'101 and 102.
  • gears depending on the position of the setting shaft 103, will come into engagement either with an axially facing, gear toothed edge segment 112a the adjusting disk 112 via a gear 1 16 mounted rotatably on the setting shaft 103, or with gear 113 of the driving mechanisms for the hands.
